RDFa 1.1 Core – Second Edition

XHTML+RDFa 1.1 – Second Edition

As the W3C website explains, “The last couple of years have witnessed a fascinating evolution: while the Web was initially built predominantly for human consumption, web content is increasingly consumed by machines which expect some amount of structured data. Sites have started to identify a page’s title, content type, and preview image to provide appropriate information in a user’s newsfeed when she clicks the ‘Like’ button. Search engines have started to provide richer search results by extracting fine-grained structured details from the Web pages they crawl. In turn, web publishers are producing increasing amounts of structured data within their Web content to improve their standing with search engines.”

“A key enabling technology behind these developments is the ability to add structured data to HTML pages directly. RDFa (Resource Description Framework in Attributes) is a technique that allows just that: it provides a set of markup attributes to augment the visual information on the Web with machine-readable hints. ”

Manu Sporny, the editor of the HTML+RDFa 1.1 specification, told us that, “The release of RDFa 1.1 for HTML5 establishes it as the first HTML-based Linked Data technology to achieve recognition as an official Web standard by the World Wide Web Consortium.” Read more
